Overriding Joomla core component file

Question

I am trying to override the com_content/views/article/view.html.php file in joomla using the instructions given in this page

It says I have to create a folder named 'code' in base directory and create the same directory structure. I tried it , but its not working. Can someone confirm whether its working.

Where should I create code folder? Is it on root of joomla installations?

PS- The edit is working correctly when applied on core file

Have you tried doing the templating method as well? – Adkison

Templating method also not working. I think templating method can only override default.php files inside tmpl folder. – Scalage

What version of Joomla are you using? – Lyndes

Answer 1

You can override (nearly) any class in Joomla, if your class with the same name is loaded first. To ensure that, you need to create a system plugin.

Here is an example for root/components/com_content/views/article/view.html.php:

class plgSystemOverride extends JPlugin
{
    public function onAfterRoute()
    {
        JLoader::register('ContentViewArticle', 'path/to/override.php', true);
    } 
}

CAVEAT: Overriding a core class can lead to problems with other extensions, if you're not very careful. For views, though, any interferrence with other extensions is less likely.

Answer 2

You can't override component controllers, models and views in core Joomla! without using a 3rd party plugin.

The plugin you need can be found here: http://extensions.joomla.org/extensions/style-a-design/templating/15611

The code folder then goes into your Joomla root unless you're overriding a back-end view in which case it goes into /administrator

Hope this helps :)
